[0002] With the continuous development of DC charging technology, the technical standards of DC charging equipment are also constantly changing. Different electric vehicles use control and guidance circuits with different charging standards. The current charging piles can only charge electric vehicles that use the same charging standard as themselves, and cannot meet the charging needs of electric vehicles with other charging standards. Summary of the invention

[0003] The present application provides a charging device, in which at least one sub-control guidance circuit is connected to a connection confirmation contact to form a control guidance circuit that complies with different charging standards, so that the charging device can charge electric vehicles with different charging standards, thereby meeting the charging needs of electric vehicles with different charging standards.

[0004] In a first aspect, a charging device is provided, comprising a plurality of sub-control guiding circuits and a connection confirmation contact, wherein at least one of the plurality of sub-control guiding circuits is used to connect to the connection confirmation contact to form a control guiding circuit that complies with different charging standards.

[0005] In the embodiment of the present application, since at least one sub-control guidance circuit is connected to the connection confirmation contact, a control guidance circuit that complies with different standards can be formed, that is, the charging device can be compatible with control guidance circuits corresponding to multiple different charging standards. Therefore, the charging device can charge electric vehicles with different charging standards, thereby meeting the charging needs of electric vehicles with different charging standards, and further improving the user experience.

[0006] In combination with the first aspect, in one embodiment, the charging device also includes a switch component, and multiple sub-control guidance circuits are connected to the connection confirmation contact through the switch component; the switch component is used to conduct the circuit between at least one sub-control guidance circuit and the connection confirmation contact.

[0007] In this way, by controlling the state of the switch of the switch assembly, the sub-control guidance circuit connected to the connection confirmation contact in the charging device can be flexibly controlled so that the charging standard of the control guidance circuit formed in the charging device is consistent with the charging standard of the control guidance circuit of the electric vehicle, which is conducive to the normal charging of the electric vehicle.

[0008] In combination with the first aspect, in one embodiment, the plurality of sub-control guiding circuits are composed of a first sub-control guiding circuit, a second sub-control guiding circuit and a third sub-control guiding circuit, wherein the first sub-control guiding circuit and the second sub-control guiding circuit include a voltage source and a resistance unit. The third sub-control guiding circuit includes a first resistor, wherein the first resistor, a first normally closed switch and at least some switches in the switch assembly are connected in series, and the first resistor, the first normally closed switch and at least some switches in series are connected between the connection confirmation contact and the device ground platform of the charging device. The voltage source of the first sub-control guiding circuit is connected to the connection confirmation contact through the resistance unit and some switches in the switch assembly, and the voltage source of the second sub-control guiding circuit is connected to the connection confirmation contact through the resistance unit, the switch in the switch assembly and the first normally closed switch, or the voltage source of the second sub-control guiding circuit is connected to the connection confirmation contact through the resistance unit and at least some switches of the switch assembly. The switch component is used to: conduct the circuit between the first sub-control guiding circuit and the connection confirmation contact and the circuit between the third sub-control guiding circuit and the connection confirmation contact to form a control guiding circuit that meets one of the charging standards; or conduct the circuit between the second sub-control guiding circuit and the connection confirmation contact to form a control guiding circuit that meets another charging standard.

[0009] In this way, the first sub-control guiding circuit and the third sub-control guiding circuit are both connected to the connection confirmation contacts to form a control guiding circuit that meets one of the charging standards, or the second sub-control guiding circuit is connected to the connection confirmation contacts to form a control guiding circuit that meets another charging standard. The circuits between different sub-control guiding circuits and the connection confirmation contacts can be flexibly connected through the switch component to form control guiding circuits that meet different charging standards, thereby improving the flexibility of the same charging device to charge electric vehicles of different standards.

[0010] In combination with the first aspect, in one embodiment, the charging device is used to: when the charging device is connected to an electric vehicle, receive a message sent by the electric vehicle to indicate a charging standard corresponding to a control guidance circuit of the electric vehicle; when the control guidance circuit currently connected to the charging device does not meet the charging standard corresponding to the control guidance circuit of the electric vehicle, control the switch component to operate so that the control guidance circuit connected to the charging device after the switch component is operated meets the charging standard corresponding to the control guidance circuit of the electric vehicle.

[0011] In this way, before the charging device is connected to the electric vehicle and the charging device transmits direct current to the electric vehicle, the charging device can determine whether the charging standard of the current control guidance circuit in the charging device meets the charging standard of the control guidance circuit of the electric vehicle by receiving a message indicating the charging standard corresponding to the control guidance circuit of the electric vehicle. If it does not meet the requirement, the charging device can control the switch component to operate so that the control guidance circuit connected to the charging device after the switch component is operated meets the charging standard corresponding to the control guidance circuit of the electric vehicle. In this way, charging abnormalities caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, thereby ensuring the normal charging of the electric vehicle.

[0012] In combination with the first aspect, in one embodiment, the first sub-control guiding circuit includes a first voltage source and a first resistance unit, the first resistance unit includes a second resistor, one end of the second resistor is connected to the first voltage source, and the other end of the second resistor is connected to the connection confirmation contact.

At least one sub-control guiding circuit can be connected to the connection confirmation contact through the switch component to form a control guiding circuit that meets one of the charging standards. When the charging device is connected to the electric vehicle, the charging circuit formed between the charging device and the electric vehicle meets the charging standard, thereby improving the reliability of the charging device charging the electric vehicle, and further improving the user experience.

[0014] In combination with the first aspect, in one embodiment, the switch assembly includes a first switch, a second switch, and a third switch, each switch includes a moving contact, a first static contact, and a second static contact, and the moving contact of each switch is used to connect its own first static contact or second static contact.

[0015] In this way, by controlling the static contact connected to the moving contact of the switch in the switch assembly, the control guidance circuit of one of the charging standards can be connected to the connection confirmation contact. When the charging device is connected to the electric vehicle, the static contact connected to the moving contact of the control switch can be used to connect the control guidance circuit that matches the control guidance circuit of the electric vehicle to the connection confirmation contact, so that the charging device can better adapt to electric vehicles with control guidance circuits of different standards.

[0018] In this way, when the charging device is connected to an electric vehicle, if the standard corresponding to the control guidance circuit of the electric vehicle is consistent with the standard corresponding to the control guidance circuit formed by the combination of the first sub-control guidance circuit, the third sub-control circuit and the first normally closed switch, the charging device can control the moving contact of each switch to connect to its own second static contact; if the standard corresponding to the control guidance circuit of the electric vehicle is consistent with the standard corresponding to the second sub-control guidance circuit, the charging device can control the moving contact of each switch to connect to its own first static contact, or control some switches to connect to their own first static contacts and some switches to connect to their own second static contacts; thereby, the charging device can better adapt to electric vehicles with control guidance circuits of different standards, which is conducive to the normal charging of electric vehicles.

[0020] In combination with the first aspect, in one embodiment, the switch assembly includes a first switch, a second switch, and a third switch, each switch includes a first static contact, a second static contact, and a moving contact, and the moving contact of each switch is used to connect its own first static contact or second static contact. In the case where the second sub-control guidance circuit includes a second voltage source and a second resistance unit, the first static contact of the first switch is connected to the first sub-control guidance circuit, the second static contact of the first switch is connected to the second static contact of the second switch, and the moving contact of the first switch is connected to the connection confirmation contact.

[0023] In this way, in the above four embodiments, by controlling the static contact connected to the moving contact of the switch in the switch assembly, the control guidance circuit of one of the charging standards can be connected to the connection confirmation contact.

[0036] With the development of new energy vehicle technology, many automobile manufacturers have gradually launched electric vehicles. Electric vehicles have become the choice of many users because of their energy saving and environmental protection as well as relatively mature technology.

[0037] The present application can be applied to a system in which a power supply device charges a load through a power distribution matrix, especially for a system including a charging pile and an electric vehicle, where the charging pile can use the electric energy from the power grid to charge the electric vehicle, so as to realize the electric energy replenishment of the electric vehicle.

[0038] Figure 1 The structural diagram of the charging system 10 provided in the embodiment of the present application is exemplified.

[0039] Combination Figure 1 (a) and Figure 1 In (b), the charging system 10 may include a charging pile 11 and an electric vehicle 12 . The charging pile 11 is used to receive the alternating current output by the power grid 20 , and convert the alternating current into direct current and transmit it to the electric vehicle 12 to charge the electric vehicle 12 .

[0040] In some embodiments, Figure 1As shown in (a), the charging pile 11 may include a charging host 111 and at least one charging terminal 112, each charging terminal 112 includes at least one charging gun 113, wherein the charging host 111 may be electrically connected to the at least one charging terminal 112.

[0041] The charging host 111 may include a plurality of power conversion devices, which may convert the AC power from the power grid 20 into DC power and transmit it to the charging terminal 112. The plurality of power conversion devices may include, for example, an alternating current-direct current (AC-DC) conversion device and a direct current-direct current (DC-DC) conversion device. The charging terminal 112 transmits the DC power to the electric vehicle 12 through the charging gun 113 to charge the electric vehicle 12.

[0042] The charging terminal 112 may include a housing, a human-machine interaction interface, a charging control unit, a metering and billing unit, etc., and is used for information exchange, energy transmission, metering and billing, etc. with the electric vehicle 12.

[0043] The electric vehicle 12 may be a vehicle driven by electric energy, such as a pure electric vehicle / battery electric vehicle (pure EV / battery EV), a hybrid electric vehicle (HEV), a range extended electric vehicle (REEV), or a plug-in hybrid electric vehicle (PHEV).

[0044] In other embodiments, Figure 1 As shown in (b), the charging pile 11 can directly set the human-machine interface, charging control unit and metering and billing unit in the charging host 111, so that the charging pile 11 can only include the charging host 111 and at least one charging gun 113 electrically connected to the charging host 111, but not the charging terminal 112. The multiple power conversion devices in the charging host 111 can convert the AC power from the external power grid 20 into DC power, and then directly transmit it to the electric vehicle 12 through the charging gun 113.

[0045] Figure 2 for Figure 1A circuit connection diagram of a charging system 10 is shown in FIG. The charging host 111 may include a plurality of AC-DC conversion devices 1111 , a plurality of DC-DC conversion devices 1112 , a DC bus 1113 and a power distribution device 1114 .

[0046] The input ends of the multiple AC-DC conversion devices 1111 are connected to the power grid 20, and the output ends of the multiple AC-DC conversion devices 1111 are connected to the DC bus 1113. That is, the multiple AC-DC conversion devices 1111 are connected in parallel between the power grid 20 and the DC bus 1113. The multiple AC-DC conversion devices 1111 can be used to receive alternating current from the power grid 20, and convert the alternating current into direct current, and then output it to the DC bus 1113.

[0047] The input end of the DC-DC converter 1112 is connected to the DC bus 1113, and the output end of the DC-DC converter 1112 is connected to the charging terminal 112 through the power distribution device 1114. The DC-DC converter 1112 receives the DC power output from the multiple AC-DC converters 1111 through the DC bus 1113, and further converts the DC power into DC power suitable for the electric vehicle 12 and transmits it to the power distribution device 1114. The power distribution device 1114 can dynamically distribute the DC power output by the multiple DC-DC converters 1112 according to the actual charging power required by the electric vehicle 12. The distributed charging power is transmitted to the electric vehicle 12 through the charging gun 113 of the charging terminal 112 to charge the electric vehicle 12.

[0048] With the continuous development of DC charging technology, the technical standards of DC charging equipment are also constantly changing. Different electric vehicles use control and guidance circuits of different standards. The current charging piles can only charge electric vehicles that use the same standard as themselves, and cannot meet the charging needs of electric vehicles of other standards.

[0049] Based on this, the present application provides a charging device, which includes control guidance circuits of different standards, so that the charging device can charge electric vehicles of different standards, thereby meeting the charging needs of electric vehicles of different standards and further improving the user experience.

[0050] like Figure 3 FIG. 1 is a schematic diagram of a charging device provided by an embodiment of the present application, wherein the charging device includes a plurality of sub-control guide circuits 310 and a connection confirmation contact CC1. Figure 3 The multiple sub-control steering circuits 310 include sub-control steering circuit 1, sub-control steering circuit 2, ..., sub-control steering circuit N, and the circuit topologies of these N sub-control circuits are different.

[0051] In the embodiment of the present application, at least one of the plurality of sub-control guiding circuits 310 is used to connect to the connection confirmation contact CC1 to form a control guiding circuit that complies with different charging standards, wherein the charging standards may include the 2015 standard, the 2015+ standard, the super charging standard, and the like.

[0052] In the embodiment of the present application, when the charging device leaves the factory, according to the needs of the customer, at least one sub-control guide circuit can be set to connect with the connection confirmation contact CC1 to meet the needs of the customer. For example, when the control guide circuit required by the customer corresponds to the 2015 standard, at least one sub-control guide circuit can be set to connect with the connection confirmation contact CC1 so that the control guide circuit currently connected to the connection confirmation contact CC1 of the charging device is a control guide circuit of the 2015 standard; when the control guide circuit required by the customer corresponds to the 2015+ standard, at least one sub-control guide circuit can be set to connect with the connection confirmation contact CC1 so that the control guide circuit currently connected to the connection confirmation contact CC1 of the charging device is a control guide circuit of the 2015+ standard. In this way, the same charging device can charge electric vehicles with different charging standards, thereby meeting the charging needs of electric vehicles with different charging standards, and thus improving the user experience.

[0053] Continue to refer Figure 3 In one embodiment, the charging device further comprises a switch component 320, and the plurality of sub-control guide circuits are connected to the connection confirmation contact CC1 through the switch component 320. The switch component 320 is used to conduct the circuit between at least one sub-control guide circuit and the connection confirmation contact CC1.

[0054] Which sub-control guide circuits are specifically turned on and the circuits between the connection confirmation contact CC1 are related to the needs of the customer. For example, when the control guide circuit required by the customer corresponds to the 2015 standard, and if the control guide circuit formed by the connection of the sub-control guide circuit 1 and the sub-control guide circuit 2 with the connection confirmation contact CC1 conforms to the control guide circuit of the 2015 standard, the switch state of at least one switch in the switch assembly can be set so that both the sub-control guide circuit 1 and the sub-control guide circuit 2 are connected to the connection confirmation contact CC1; when the control guide circuit required by the customer corresponds to the 2015+ standard, and if the control guide circuit formed by the connection of the sub-control guide circuit 3 with the connection confirmation contact CC1 conforms to the control guide circuit of the 2015+ standard, the switch state of at least one switch in the switch assembly can be set so that the sub-control guide circuit 3 is connected to the connection confirmation contact CC1. In this way, the same charging device can charge electric vehicles of different standards, thereby meeting the charging needs of electric vehicles of different standards. Moreover, by controlling the state of the switch of the switch assembly, the sub-control guidance circuit connected to the connection confirmation contact CC1 in the charging device can be flexibly controlled so that the charging standard of the control guidance circuit formed in the charging device is consistent with the charging standard of the control guidance circuit of the electric vehicle, which is conducive to the normal charging of the electric vehicle.

[0055] In one embodiment, Figure 4 As shown, the multiple sub-control guiding circuits include a first sub-control guiding circuit 310a, a second sub-control guiding circuit (the second sub-control guiding circuit is 310b or 310c shown in the figure) and a third sub-control guiding circuit 310d, and the first sub-control guiding circuit 310a and the second sub-control guiding circuit 310b or 310c both include a voltage source and a resistance unit. The third sub-control guiding circuit 310d includes a first resistor R2, the first resistor R2, the first normally closed switch S, and at least some switches in the switch component 320 are connected in series, and the first resistor R2, the first normally closed switch S, and at least some switches in series are connected between the connection confirmation contact CC1 and the device ground platform PE of the charging device.

[0056] The voltage source U1a of the first sub-control steering circuit 310a is connected to the resistor unit (including Figure 4 R1a) shown in FIG. 1 and some switches in the switch assembly are connected to the connection confirmation contact CC1, and the voltage source U1b of the second sub-control steering circuit 310b is connected through the resistor unit (including Figure 4 The resistors R1b, R2b', switch S1b shown in FIG. 3 ), the switch in the switch assembly 320 and the first normally closed switch S are connected to the connection confirmation contact CC1, or the voltage source U1c of the second sub-control steering circuit 310c is connected to the connection confirmation contact CC1 through the resistor unit (including Figure 4The resistors R1c, R1c', switches S0c, S1c shown in FIG. 1 ), at least part of the switches of the switch assembly are connected to the connection confirmation contact CC1.

[0057] In the embodiment of the present application, the switch component 320 is used to: conduct the circuit between the first sub-control guiding circuit 310a and the connection confirmation contact CC1 and the circuit between the third sub-control guiding circuit 310d and the connection confirmation contact CC1 to form a control guiding circuit that meets one of the charging standards; or conduct the circuit between the second sub-control guiding circuit 310b or 310c and the connection confirmation contact CC1 to form a control guiding circuit that meets another charging standard.

[0058] In the embodiment of the present application, when the switch component 320 conducts the circuit between the first sub-control guiding circuit 310a and the connection confirmation contact CC1 and the circuit between the third sub-control guiding circuit 310d and the connection confirmation contact CC1, the control guiding circuit formed at this time is a control guiding circuit of the 2015 standard. When the switch component 320 conducts the circuit between the second sub-control guiding circuit 310b, the first normally closed switch S and the connection confirmation contact CC1, the control guiding circuit formed at this time is a control guiding circuit of the 2015+ standard. When the switch component 320 conducts the circuit between the second sub-control guiding circuit 310c and the connection confirmation contact CC1, the control guiding circuit formed at this time is a control guiding circuit of the super charging standard. In this way, the switch component 320 can flexibly conduct the circuits between different sub-control guiding circuits and the connection confirmation contacts to form control guiding circuits that meet different charging standards, thereby improving the flexibility of the same charging device to charge electric vehicles of different standards.

[0059] In one embodiment, continue to refer to Figure 4 The first sub-control steering circuit 310a includes a first voltage source U1a and a first resistance unit, the first resistance unit includes a second resistor R1a, one end of the second resistor R1a is connected to the first voltage source U1a, and the other end of the second resistor R1a is connected to the connection confirmation contact CC1.

[0061] Among them, each sub-control guiding circuit corresponds to part or all of the circuits in the control guiding circuit of different standards. The first sub-control guiding circuit 310a corresponds to part of the circuit in the control guiding circuit of the 2015 standard, and the third sub-control guiding circuit 310d corresponds to part of the circuit in the control guiding circuit of the 2015 standard; the second sub-control guiding circuit 310b corresponds to part of the circuit in the control guiding circuit of the 2015+ standard, or the second sub-control guiding circuit 310c corresponds to the control guiding circuit of the super charging standard. At least one sub-control guiding circuit can be connected to the connection confirmation contact CC1 through the switch component to form a control guiding circuit that meets one of the charging standards. When the charging device is connected to the electric vehicle, the charging circuit formed between the charging device and the electric vehicle meets the charging standard, thereby improving the reliability of the charging device charging the electric vehicle, and further improving the user experience.

[0062] In the embodiment of the present application, the switch in the switch assembly 320 may be a selection switch, which may include a moving contact and multiple static contacts, the moving contact may be connected to the multiple static contacts, and the static contacts connected to the moving contact may be controlled to control the connection between different sub-control guide circuits and the connection confirmation contact CC1 of the charging device. Alternatively, the switch in the switch assembly 320 may also be multiple non-selective switches, which include a moving contact and static contacts, and the connection between different sub-control guide circuits and the connection confirmation contact CC1 of the charging device may be controlled by controlling the conduction state of the two non-selective switches.

[0063] The following takes the selection switch as an example to introduce the case where the multiple control steering circuits include at least two control steering circuits.

[0064] In one embodiment, Figure 5 As shown, the switch assembly 320 includes a first switch 320a, a second switch 320b, and a third switch 320c. Each switch includes a moving contact, a first stationary contact, and a second stationary contact. The moving contact of each switch is used to connect to its own first stationary contact or second stationary contact.

[0065] In the case where the second sub-control pilot circuit 310b includes the second voltage source U1b and the second resistor unit, the first static contact 320a1 of the first switch 320a is connected to the second sub-control pilot circuit 310b, the second static contact of the first switch 320a is connected to the first sub-control pilot circuit 310a, and the moving contact 320a3 of the first switch 320a is connected to the moving contact 320b3 of the second switch 320b. The first static contact 320b1 of the second switch 320b is connected to the first static contact 320c1 of the third switch 320c, the second static contact 320b2 of the second switch 320b is connected to the connection confirmation contact CC1, the second static contact 320c2 of the third switch 320c is connected to the device ground platform through the first resistor R2, and the moving contact 320c3 of the third switch 320c is connected to the connection confirmation contact CC1 through the first normally closed switch S.

[0066] In the embodiment of the present application, when the moving contact of each switch is connected to its own second static contact, that is, when the moving contact 320a3 of the first switch 320a is connected to the second static contact 320a2, the moving contact 320b3 of the second switch 320b is connected to the second static contact 320b2, and the moving contact 320c3 of the third switch 320c is connected to the second static contact 320c2, the first sub-control guidance circuit 310a is connected to the connection confirmation contact CC1, and the third sub-control guidance circuit 310d is connected to the connection confirmation contact CC1 through the first normally closed switch S, thereby forming a control guidance circuit that complies with the 2015 standard.

[0067] When the moving contact of each switch is connected to its own first static contact, that is, when the moving contact 320a3 of the first switch 320a is connected to the first static contact 320a1, the moving contact 320b3 of the second switch 320b is connected to the first static contact 320b1, and the moving contact 320c3 of the third switch 320c is connected to the first static contact 320c1, the second sub-control guidance circuit 310b is connected to the connection confirmation contact CC1 through the first normally closed switch S, and the circuit between the third sub-control guidance circuit 310d and the connection confirmation contact CC1 is disconnected, thereby forming a control guidance circuit that complies with the 2015+ standard.

[0068] In this way, by controlling the static contact connected to the moving contact of each switch, the switching of the control guidance circuit of the 2015 standard or the 2015+ standard can be achieved, so that the control guidance circuit matching the control guidance circuit of the electric vehicle is connected to the connection confirmation contact CC1, so that the charging device can better adapt to electric vehicles with control guidance circuits of different standards. In this way, charging abnormalities caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, which is beneficial to the normal charging of the electric vehicle, and then to improving the user experience.

[0069] In addition, in the embodiment of the present application, a part of the switches can be designed to be located in the charging host and the other part can be designed to be located in the charging gun. When the first switch 320a is located in the charging host and the second switch 320b and the third switch 320c are located in the charging gun, since the moving contact 320a3 of the first switch 320a is only connected to the moving contact 320b3 of the second switch 320b, it is equivalent to having only one connecting line between the charging host and the charging gun. This can simplify the wiring method between the charging host and the charging gun, and the wiring is simple and easy to implement.

[0070] It should be noted that Figure 5 Taking the second sub-control steering circuit 310b including the second voltage source and the second resistance unit as an example, Figure 6 The second sub-control steering circuit 310c includes a third voltage source and a third resistor unit. In this case, the connection relationship between each switch and each sub-control steering circuit is the same as the above Figure 5 Similar, no further elaboration.

[0071] refer to Figure 6 When the moving contact of each switch is connected to its own second stationary contact, the first sub-control guidance circuit 310a is connected to the connection confirmation contact CC1, and the third control guidance circuit 310d is connected to the connection confirmation contact CC1 through the first normally closed switch S, thereby forming a control guidance circuit that complies with the 2015 standard.

[0072] When the moving contacts of the first switch 320a and the third switch 320c are connected to their own first static contacts, and the second switch 320b is connected to its own second static contact, that is, the moving contact 320a3 of the first switch 320a is connected to the first static contact 320a1, the moving contact 320c3 of the third switch 320c is connected to the first static contact 320c1, and the moving contact 320b3 of the second switch 320b is connected to the second static contact 320b2, the second sub-control guidance circuit 310c is connected to the connection confirmation contact CC1 and the circuit between the third sub-control guidance circuit 310d and the connection confirmation contact CC1 is disconnected, thereby forming a control guidance circuit that meets the supercharging standard.

[0073] In this way, by controlling the static contact connected to the moving contact of each switch, the switching of the control guidance circuit of the 2015 standard or the supercharging standard can be achieved, so that the control guidance circuit matching the control guidance circuit of the electric vehicle is connected to the connection confirmation contact CC1, so that the charging device can better adapt to electric vehicles with control guidance circuits of different standards. In this way, charging abnormalities caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, which is beneficial to the normal charging of the electric vehicle, and then to improving the user experience.

Each switch includes a moving contact, a first stationary contact, and a second stationary contact. The moving contact of each switch is used to connect to its own first stationary contact or second stationary contact.

The first static contact 320b1 of the second switch 320b is connected to the first static contact 320a1 of the first switch 320a, the moving contact 320b3 of the second switch 320b is connected to the moving contact 320c3 of the third switch 320c through the first normally closed switch S, the first static contact 320c1 of the third switch 320c is connected to the equipment ground platform PE through the first resistor R2, and the second static contact 320c2 of the third switch 320c is connected to the second sub-control pilot circuit 310b.

[0077] When the moving contact of each switch is connected to its own second static contact, that is, when the moving contact 320a3 of the first switch 320a is connected to the second static contact 320a2, the moving contact 320b3 of the second switch 320b is connected to the second static contact 320b2, and the moving contact 320c3 of the third switch 320c is connected to the second static contact 320c2, the second sub-control guidance circuit 310b is connected to the connection confirmation contact CC1 through the first normally closed switch S, and the circuit between the third sub-control guidance circuit 310d and the connection confirmation contact CC1 is disconnected, thereby forming a control guidance circuit that complies with the 2015+ standard.

[0078] In this way, by controlling the static contact connected to the moving contact of each switch, the switching of the control guidance circuit of the 2015 standard or the 2015+ standard can be achieved, so that the control guidance circuit matching the control guidance circuit of the electric vehicle is connected to the connection confirmation contact CC1, so that the charging device can better adapt to electric vehicles with control guidance circuits of different standards. In this way, charging abnormalities caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, which is beneficial to the normal charging of the electric vehicle, and then to improving the user experience.

[0079] In addition, in the embodiment of the present application, the switches in the switch assembly can be designed to be located in the charging host. When the switches in the switch assembly are located in the charging host, since the moving contact 320c3 of the third switch 320c is only connected to the connection confirmation contact CC1, it is equivalent to having only one connecting line between the charging host and the charging gun. This can simplify the wiring method between the charging host and the charging gun, and the wiring is simple and easy to implement.

[0096] In the embodiment of the present application, by controlling the static contact connected to the moving contact of each switch, the switching of the control guidance circuit of the 2015 standard, the 2015+ standard or the super charging standard can be realized, so that the control guidance circuit matching the control guidance circuit of the electric vehicle is connected to the connection confirmation contact CC1, so that the charging device can better adapt to the electric vehicles with control guidance circuits of different standards. In this way, the charging abnormality caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, which is conducive to the normal charging of the electric vehicle, and further to the improvement of user experience. Moreover, since the fourth sub-control guidance circuit is connected to the connection confirmation contact to form another control guidance circuit that meets the standard, the charging device can charge electric vehicles with more charging standards, thereby improving the competitiveness of the charging device, and further facilitating the further development and application of the charging device.

[0097] In one embodiment, the charging device may also include a second sub-control steering circuit 310b and a fourth sub-control steering circuit 310c, such as Fig.13 As shown, by controlling the static contact connected to the moving contact of the switch in the switch assembly, the second sub-control guiding circuit or the fourth sub-control guiding circuit can be connected to the connection confirmation contact CC1, thereby forming a control guiding circuit that complies with the 2015+ or supercharging standard.

The moving contact 320a3 is used to connect the first static contact 320a1 or the second static contact 320a2.

[0099] When the second sub-control steering circuit 310b includes a second voltage source U1b and a second resistance unit, and the fourth sub-control steering circuit 310c includes a third voltage source U1c and a third resistance unit, the first static contact 320a1 of the first switch 320a is connected to the second sub-control steering circuit 310b through the first normally closed switch S, and the second static contact 320a2 of the first switch 320a is connected to the fourth sub-control steering circuit.

In this way, the switching of the control guidance circuit of the 2015+ standard or the supercharging standard can be achieved, so that the control guidance circuit that matches the control guidance circuit of the electric vehicle is connected to the connection confirmation contact CC1, so that the charging device can better adapt to the electric vehicle with control guidance circuits of different standards. In this way, the charging abnormality caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, which is beneficial to the normal charging of the electric vehicle, and further to the improvement of the user experience.

[0101] Fig.14 The switch assembly includes two non-selective switches. Fig.14 and Figure 7 The only difference is the switch of the switch component. The specific control logic is the same as above. Figure 7 Similarly, for the sake of brevity, no further description is given. Similarly, the selection switches in the above embodiments can be replaced by a plurality of non-selection switches, and the specific control logic remains unchanged.

[0102] Based on this, the above introduces different specific circuit topologies of multiple control guidance circuits that may be included in the charging device, and the following briefly introduces the control logic of the charging device. In one embodiment, the charging device is used to: when the charging device is connected to an electric vehicle, receive a message sent by the electric vehicle to indicate the charging standard corresponding to the control guidance circuit of the electric vehicle; when the control guidance circuit currently connected to the charging device does not meet the charging standard corresponding to the control guidance circuit of the electric vehicle, control the switch component to operate so that the control guidance circuit connected to the charging device after the switch component is operated meets the charging standard corresponding to the control guidance circuit of the electric vehicle.

[0103] With the above Figure 5For example, assuming that the charging device is set to connect the first sub-control guidance circuit 310a to the connection confirmation contact CC1 when leaving the factory, and the third sub-control guidance circuit 310d is connected to the connection confirmation contact CC1 to form a control guidance circuit that complies with the 2015 charging standard. When the charging device is connected to the vehicle to be charged, the vehicle to be charged sends a message indicating the standard of the control guidance circuit of the electric vehicle to the charging device. If the standard of the control guidance circuit of the vehicle to be charged is also the 2015 standard, the charging device can charge the vehicle to be charged normally; if the standard of the control guidance circuit of the vehicle to be charged is the 2015+ standard, the charging device can control the switch component to operate to form a control guidance circuit that complies with the 2015+ charging standard, and on this basis, complete the charging of the vehicle to be charged. In this way, charging abnormalities caused by the mismatch between the control guidance circuit of the charging device and the control guidance circuit of the electric vehicle can be prevented, thereby ensuring the normal charging of the electric vehicle, which is beneficial to improving the user experience. For specific control logic, please refer to the above Figure 5 The relevant content will not be repeated here.

[0104] In one embodiment, the charging device may not include a switch assembly, and the charging device includes a plurality of sub-control guidance circuits, a plurality of connection points, and a connection confirmation contact CC1. When the charging device leaves the factory, according to customer needs, at least one sub-control guidance circuit may be set to be connected to the connection confirmation contact CC1 to form a control guidance circuit that meets different charging standards. Since the charging device is compatible with a plurality of control guidance circuits of different charging standards, the charging device can charge electric vehicles of different charging standards, thereby meeting the charging needs of electric vehicles of different charging standards.

[0105] Take the charging equipment including the control and guidance circuit of the 2015 standard and the control and guidance circuit of the 2015+ standard as an example, refer to Fig.15, these multiple connection points include 330a1~330a3, 330b1~330b3, 330c1~330c3. When the customer needs a charging device with the 2015 charging standard, the connection points 330a1 and 330a3 can be set to be connected, and 330c2 and 330c3 can be connected, so that the charging device can charge electric vehicles with the 2105 charging standard. When the customer needs a charging device with the 2015+ charging standard, the connection points 330a2 and 330a3 can be set to be connected, 330b3 and 330b1 can be connected, and 330c1 and 330c3 can be connected, so that the charging device can charge electric vehicles with the 2105+ charging standard. In this way, the charging device can meet the charging needs of electric vehicles with different standards. In addition, since the embodiment of the present application does not involve a switch assembly, it can prevent the switch damage caused by the moving contact of the switch in the switch assembly repeatedly switching different static contacts, thereby preventing the charging device from being able to charge the electric vehicle, thereby improving the reliability of the charging device charging the electric vehicle.

[0106] It should be understood that Fig.15 In the charging device shown, once the charging device leaves the factory, the charging device can only charge electric vehicles with corresponding charging standards. When the charging standard of the control guidance circuit of the electric vehicle is different from the charging standard of the control guidance circuit of the charging device, the charging device cannot switch to the charging standard of the control guidance circuit corresponding to the electric vehicle.

[0107] It should be noted that in the above Figures 4 to 15 The positions of the first normally closed switch S and the first resistor R2 are not specifically limited. The first normally closed switch S and the first resistor R2 may both be located in the charging host or both be located in the charging gun. Alternatively, one of the first normally closed switch S and the first resistor R2 may be located in the charging host, and the other may be located in the charging gun.

[0108] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
